303/TR3

      The 303/TR3 has five features.The first one is that it can reduce PCB space requirements.The second one is about direct solderable or plug-in versions.The third one is that the 303/TR3 is internationally approved by UL and CSA.The fourth one is about low internal resistance.The fifth one is about shicksafe casing.The last one is about vibration resistant.
      The following is about the specifications of 303/TR3.Its packaging is three.The 1st one is marked 000 which is tape/ammopack(1500 pcs.).The 2nd one is marked 013 which is long leads-bulk(200 pcs.)The 3rd one is marked 042 which is short leads-bulk(300 pcs.)The material of base/cap is black thermoplastic base polyamide PA 6.6,UL 94V0 brass and nickel-plated cap.The material of round pins is copper alloy and tin plated.The operating temperature is from -25ºC to +70 ºC (consider de-rating).The cclimatic category is -25 ºC/+70 ºC/21 days (EN 60068-1,-2-1,-2-2,-78).The stock conditions is +10 ºC to +60 ºC,relative humidity 75 % yearly average and without dew, maximum value for 30 days-95 %.Vibration resistance is 24 cycles at 15 min. each (EN 60068-6),10 - 60 Hz at 0.75 mm amplitude and 60 - 2000 Hz at 10 g acceleration.Lead pull strength is 10 N (EN 60068-2-21).Solderability is 260 ºC, 3 s (Wave) and 350 ºC, 1 s (Soldering Iron).Soldering heat resistance is 260 ºC and 10 s (IEC 60068-2-20).Unit weight is 0.40 g (approx.).Time-Current characteristic is Quick Acting (F).The standard of 303/TR3 is UL 248-14 and CSA C22.2 No. 248.14.
