Product Overview
RCD Components 175-5000-FBQ — a 500 Ohm, 10 Watt, 1% tolerance wirewound power resistor on a ceramic core with silicone coating. Axial-leaded for through-hole mounting. Built for applications where precision and power handling matter: current limiting, load testing, voltage divider stages, and motor control circuits that demand stable resistance under heat and continuous load.
Key Features
- Resistance: 500 Ohm
- Power rating: 10W
- Tolerance: 1%
- Construction: Wirewound on ceramic core, silicone coated
- Lead style: Axial leaded, through-hole mount
- Body markings: RCD 175, 500 Ohm 1%, R0612
Applications
- Replacing a failed power resistor in a motor control board — desoldering the burnt component, confirming 500 Ohm at 10W, and dropping this in as a direct replacement to bring the drive back online
- Building a precision load bank for power supply verification in a lab or repair shop where a stable 500 Ohm reference at 10W keeps measurements honest
- Integrating into a voltage divider or current-limiting stage in an industrial automation panel where resistance drift under heat would cause downstream faults
- Makers and hobbyists using this as a dummy load for testing amplifier or power supply output on the bench — sturdy enough to absorb real power without complaint
- Audio DIY builds where a high-wattage precision resistor is needed in a bias or bleeder circuit and a film resistor would overheat
Frequently Asked Questions
Is this a new or used part?
Unused NOS — unissued stock sourced from a distributor that was consolidating inventory. The body is clean with no signs of installation or use.
What is the tolerance and is it suitable for precision work?
Tolerance is 1%, confirmed by marking on the body. That makes it suitable for current-limiting, load testing, voltage divider, and calibration support applications where a standard 5% carbon film resistor would not hold close enough.
Does this have any inductance concerns for high-frequency circuits?
Wirewound resistors inherently carry some parasitic inductance. For DC, low-frequency, and moderate-frequency power applications this is not a practical concern. For high-frequency AC circuits where inductance must be tightly controlled, verify whether a non-inductive wirewound variant is required for your application.
What are the physical dimensions?
Total span including leads is approximately 120mm based on the part itself. Exact body dimensions are not confirmed — measure your available board or chassis space before ordering if clearance is tight.
Is a datasheet or documentation included?
Not included. This is a surplus component sale only.
A 500 Ohm wirewound at 10W and 1% is the kind of part a good tech keeps on the shelf — precise enough for lab work, tough enough for the chassis. Yours now, ready to go back to work.
