Product Overview
Vishay Dale's WSC-1 is a 1 watt wirewound resistor of all-welded construction, molded in epoxy with wraparound terminals so it solders flat to a 2515 footprint. This one is 10 Ω at ±1% with a ±50 ppm/°C temperature coefficient.
Key Features
- Resistance: 10 Ω, ±1% tolerance
- Power rating: 1.0 W at 70 °C
- Temperature coefficient: ±50 ppm/°C
- Operating temperature: -65 °C to +175 °C
- Construction: wirewound, all welded, molded epoxy body
- Size: 2515; body 6.35 x 3.81 x 2.79 mm (0.250 x 0.150 x 0.110 in) nominal
- Terminals: wraparound, for surface mount soldering
Applications
- Current sensing on a low-current rail, where 100 mA drops 1 V across it
- Replacing a WSC-1 on a board laid out for Dale 2515 power resistors
- Series current limiting on a supply rail that needs a full watt in a surface mount footprint
Frequently Asked Questions
How does WSC-1 relate to WSC0001 and WSC2515?
WSC-1 is Vishay Dale's older model name for the 1 W WSC in the 2515 size. WSC0001 is its global model name.
Will it fit a 2515 footprint?
Yes. The body is 2515 size, 6.35 mm long and 3.81 mm wide, with a wraparound terminal at each end.
How much current can it carry at its full rating?
Up to 316 mA at 70 °C. That current puts the full 1 W across 10 Ω and drops 3.16 V.
Resistance wire, welded and sealed in molded epoxy: the WSC-1 is the old way to make a precise resistor, shrunk down to sit flat on a board. Paste on both 2515 pads and a pass of hot air is the whole installation.
