• Manufacturer Part Number: DSC
• Description: Double-Sided Chip Resistors
• Manufacturer: WELWYN [Welwyn Components Limited]

Double Sided
Chip Resistors
DSC Series
Note: A 0.01 Ohm addition to be added to the performance of all resistors <10 Ohms.
Lightning Surge
Resistors have been tested in
accordance with IEC 60 115-1 using
both 1.2/50µs and 10/700µs pulse
shapes. Also, the 2512 size has
been tested to the Bellcore GR1089
2/10µs and 10/1000µs pulse shapes.
The limit of acceptance is a shift
in resistance of less than 1% from
the initial value.
