(P-JHC-E010/1） Type JHC TYPE JHC High Current Micro Fuse is designed for the purpose of external short circuit protection of the lithium ion battery of medium sizes, such as a power tool and an electric assistant bicycle. Though it was a surface mount type, it was small and realized high current rating, because a fuse element and a terminal adopt the structure of one. Furthermore perfectly compliant to Lead-free makes environment friendly design. FEATURES 1. High current rating was realized because a fuse element and a terminal adopt the structure of one. 2. Surface mount type and small size of 7358 (7.3mm × 5.8mm × 4.2mm) and 1173 (11.0mm × 7.3mm × 5.9mm). 3. Surface temperature rise is 75°C or less when applying rated current. This gives little influence to the peripheral units. 4. Alumina ceramics are adopted as a case, original structure is adopted as the inside of a case, and the safety at the time of fusing is improved. 5. Suitable for automatic mounting 6.

If you select the micro fuse , safety of your circuit can be ensured. How to determine the rated value of the micro fuse is described below: ■Flow for fuse selection 1. Measurement of circuit values using actual device Measure the circuit values, such as operating current of the circuit. 2. Calculation from operating current From the obtained operating current and the category temperature, calculate minimum rated value to determine the applicable fuse. 3. Calculation from overload current From the obtained overload current, calculate the maximum rated value to determine the applicable fuse. 4. Calculation from inrush current From the inrush current, calculate the minimum rated value to determine the applicable fuse. 5. Final determination of rated value From the calculation results of steps 2 through 4, determine the rated value. 6. Operation check using actual device After selecting the rating, confirm if the device works properly under the pre-determined conditions. ■Fuse selection 1. Measurement of circuit values using actual device Before determining the rated value of the fuse, preliminarily measure the following condition by using the actual device. 1-1. Operating current Using an oscilloscope or equivalents, measure operating current of the circuit. 1-2. Overload current Using an oscilloscope or equivalents, measure the overload current that needs to break the circuit. 1-3. Inrush current Using an oscilloscope or equivalents, measure the inrush current of circuit at power-on or power-off. In addition, determine the number of inrush current applied. 1-4．Category temperature Measure the ambient temperature of the fuse circuit. In a 25℃ environment under normal circumstances, please design substrate wiring so that the surface temperature of a fuse does not exceed 80℃. EXAMPLE TO SELECT RATINGS OF TYPE JHC Effective operating current : 30 A 300A Effective overload current : 140 A Inrush current waveform : Fig. A (Pulse width : 2 ms, Wave height : 300 A) Numbers to withstand inrush current : 100,000 times 2ms Category temperature : 85°C Fig. A：Inrush current waveform Operating time：4,000h 2. Calculation from operating current 2–1. Measurement of operating current Using an oscilloscope or equivalents, measure operating current (effective current) of the actual circuit. Example : Effective operating current = 30 A Fig. B 2–2 Derating 140 Using Fig. B, find the temperature derating factor correspond to the Temperature. However, in order to be allowed to check an operating condition in use to the apparatus used for a long time that the operating time exceeds 4,000 h, please ask our Sales Department. ②Rated derating factor Rated derating factor = 0.94 (Constant irrespective of temperature) Derating factor (%) ①Temperature derating factor 120 100 80 60 40 20 0 -50 JHC temperature derating -25 0 25 50 75 Temperature（℃） Use Formula 1 to calculate the rated current of the fuse to be used for the circuit.

Type JHC, with rated current of 50 A and 40A can be selected. 3. Calculation from overload current 3–1 Measurement of overload current Using oscilloscope or equivalents, measure overload current that needs to break circuit. Example : Effective overload current = 140 A 3–2 Calculation from overload current Determine rated current so that overload current can be 2.5 times larger than rated current. Use Formula 2 to calculate rated current of fuse. Rated current of fuse ≤ Overload current/2.5 ... Formula 2 Example : Overload current = 140 A Use Formula 2 to calculate the rated current. Rated current ≤ 140/2.5 = 56 A The above calculation result shows that the fuse with rated current of 56 A or less should be selected for this circuit. Type JHC, with rated current of 50 A and 40A can be selected. 4. Calculation from inrush current 4–1 Measurement of inrush current waveform Using an oscilloscope or equivalent, measure waveform of inrush current of actual circuit. 4–2 Creation of approximate waveform Generally, waveform of inrush current is complicated. For this reason, 300A create the approximate waveform of inrush current as shown on Fig. C to simplify calculation. 2ms 4–3 Calculation of I2t of inrush current 2 Calculate I t (Joule integral) of approximate waveform. The formula for this calculation depends on the approximate waveform. Refer to Table A. Fig. C：Inrush current waveform Red line : Actual measurement waveform Black line：Approximate waveform Example : Pulse applied = 2 ms, Peak value = 300 A Approximate waveform = Triangular wave Since the approximate waveform is a triangular wave, use the following formula for calculation. I2t of rush current = 1/3 × Im2 × t ... Formula 3 (Im : Peak value, t : Pulse applying time) Use Formula 3 to calculate I2t of the inrush current: I2t = 1/3 × 300 × 300 × 0.002 = 60 (A2s) JOULE-INTEGRAL VALUES FOR EACH WAVEFORM Name Waveform Sine wave （1cycle） 0 t m 1 m2 t 2 Sine wave （half cycle） 0 m 0 t2 Trapezoidal wave m 0 2 Waveform I t m 0 t1 t2 t3 Various wave 1  0 1 2 wave 2 2 0 m2 t discharge waveform t 2 * Following formula is generally used for calculation of I t as i(t) equal to current. 2 t＝∫0ｔｉ2（t）dt 8 t1 t2 1 t3 -t/τ  m i (t) =  m e 0.368 1 m2 t1 + m2 (t2-t1) + 3 1 m2 (t -t ) 3 2 3  1 2 t + 1 (1-2) 2 t 3 t Various 1 m2 t 3 Charge/ Rectangular wave Table Ａ Name t Triangular wave I t 1 m2 t 2 m 1 2 2 m 0 τ -t 1 2 1  1 t1+{12+ (1-2) 2} 3 1 32 (t2-t1)+  2 (t3-t2) 3 1 m2 τ 2 4-4 Search of load ratio PULSE RESISTANCE CHARACTERISTICS ①Set up number of cycles to withstand.

Joule Integral (A2s) Since the rush pulse applied is 2 ms, obtain the intersection of 2 ms (horizontal axis) and 171.4 A2s (vertical axis) from Fig. E (refer to the arrow shown in Fig. E). Select a fuse whose curve is above the intersection. Type JHC with rated current of 50 A and 40A should be selected. 5.
