Use the device title and drop the “T1” suffix when ordering any of these devices in bulk. PARAMETER TEST METHODS 4.T CC,DIODE CAPACITANCE TEMPERATURE COEFFICIENT TCC is guaranteed by comparing CT at VR=4.0Vdc,f=1.0MHz, TA= – 65°C with CT at VR=4.0Vdc,f=1.0MHz,TA= +85°C in the following equation,which defines TC C: CT(+85°C) – CT(–65°C ) 106 . TC C = 85+65 C T(25°C) Accuracy limited by measurement of CT to±0.1pF. 1. C T , D IODE CAPACITANCE (C T = C C + C J ). C T is measured at 1.0 MHz using a ca-pacitance bridge (Boonton Electronics Model 75A or equivalent). 2. T R, TUNING RATIO T R is the ratio of C T measured at 2.0 Vdc divided by C T measured at 30 Vdc. 3. Q, FIGURE OF MERIT Q is calculated by taking the G and C readings of an ad-mittance bridge at the specified frequency and substitut-ing in the following equations: Q= 2πfC G (Booton Electronics Model 33As8 or equivalent).Use Lead Length ~1/16”. ~ MMBV2101~MMBV2109 –2/3 MV2101~MV2115 LESHAN RADIO COMPANY, LTD.
