4. Marking
(1) For TC02 size. Due to the very TC02 small size
of the resistor’s body, there is no marking on the
body.
(2) For TC05、TC06、TC07、TC10、TC12 size.
±0.1%、0.25%、±0.5%、±1% Tolerance:
4 codes.
1st~3rd codes are the significant figures of resistance value,
and the rest code is the power of ten.
Letter "R" in mark means decimal point.
2701 2.7K
(3) Standard E-96 series values of TC03 ≤1% : due to the small size of the resistor’s body, 3 digits marking will be used to indicate the accurate
resistance value by using the following multiplier & resistance code.

8. Derating Curve
Power rating will change based on continuous load at ambient temperature from -55 to 155℃.
It is constant between -55 to 70℃, and derate to zero when temperature rise from 70 to 155℃.
Voltage rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or an approximate sine-wave
root-mean-square (RMS) alternating-current (AC) continuous working voltage at commercial-line
frequency and waveform corresponding to the power rating, as determined from the following formula:
√
Remark: RCWV: Rating Continuous Working Voltage (Volt.) P: power rating (Watt)
R: nominal resistance (Ω)
In no case shall the rated DC or RMS AC continuous working voltage be greater than the applicable maximum value.
The overload voltage is 2.5 times RCWV or Max. Overload voltage whichever is lower.

13. Note
13.1. UNI-ROYAL recommend products store in warehouse with temperature between 15 to 35℃ under humidity between 25 to 75%RH.
Even under storage conditions recommended above, solder ability of products will be degraded stored over 1 year old.
13.2. Cartons must be placed in correct direction which indicated on carton, otherwise the reel or wire will be deformed.
13.3. Storage conditions as below are inappropriate:
a. Stored in high electrostatic environment
b. Stored in direct sunshine, rain, snow or condensation.
c. Exposed to sea wind or corrosive gases, such as Cl2, H2S, NH3, SO2, NO2, Br etc.
13.4 After the surface of TC series high resistance resistors is coated with flux, the resistance value may be affected (exceeding the resistance
value range). After the customer's evaluation, if necessary, corresponding cleaning measures can be taken to restore the resistance. In addition,
if the surface of the resistor needs to be coated with other substances, the client needs to evaluate the impact on the product to avoid any
impact during use.
