Wrap-around terminations have an electroplated nickel barrier and solder coating, this ensures excellent ‘leach’ resistance properties and solderability. Marking Components are not marked. Reels are marked with type, value, tolerance, date code and quantity. Solvent Resistance The body protection is resistant to all normal industrial cleaning solvents suitable for printed circuits.

The single impulse graph is the result of 50 impulses of rectangular shape applied at one minute intervals. The limit of acceptance was a shift in resistance of less than 1% from the initial value. Continuous Load Due to Repetitive Pulses The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average power dissipated in the resistor was equal to its rated power at 70°C. Again the limit of acceptance was a shift in resistance of less than 1% from the initial value PWC Series Issue January 2009 Advanced Film Division • 4222 South Staples Street • Corpus Christi Texas 78411 USA Telephone: 361 992 7900 • Facsimile: 361 992 3377 • Website: www.irctt.com Pulse Voltage 100 1000 10000 0.0001 0.0010 .010 .1 1 Pulse Duration (seconds) Pulse Voltage (Volts) 0805 1206 2010 2512 Continuous Pulses 0.1 100 0.0001 0.0010 .010 .11 Pulse Duration (seconds) Pulse Power (watts) 0805 1206 2010 2512 Single Pulse 100 1000 0.0001 0.0010 .010 .1 1 Pulse duration (seconds) Pulse Power (watts) 0805 1206 2010 2512 Single impulse: The single impulse graph is the result of 50 impulses of rectangular shape applied at one minute intervals.

For soldered resistors, the joint temperature should not exceed 110°C. This condition is met when the stated power levels at 70°C and recommended pad and trace areas are used. Allowance should be made if smaller areas of copper are used. A full Application Note on the PWC Series is available. Packaging 0805 and 1206 resistors are supplied on 8mm carrier tape and 2010 and 2512 resistors are supplied on 12mm carrier tape, all on 7 inch reels as per IEC 286-3.
