Reels are marked with type, are screen printed on a 96% alumina substrate. Wrap-around value, tolerance, date code and quantity. terminations have an electroplated nickel barrier and solder coating, this ensures excellent leach resistance properties Solvent Resistance and solderability. The body protection is resistant to all normal industrial cleaning solvents suitable for printed circuits. Note that anti-sulphur version parts below 100R are produced in flip-chip format with the resistor element on the underside.

Pulse Performance Data Pulse Performance Data Lightning Surge lightning surge resistors are tested in accordance with IEC 60 115-1 using both 1.2/50s and 10/700s pulse shapes. 10 pulses are applied. The limit of acceptance is a shift in resistance of less than 1% from the initial value. 2512 2010 1206 0805 0603 Lightning Surge lightning surge resistors are tested in accordance with IEC 60 115-1 using both 1.2/50s and 10/700s pulse shapes. 10 pulses are applied.
