Description
RC0402FR-0751KL is a fixed, surface-mount resistor in the 0402 (1.0 × 0.5 mm) footprint from the RC0402FR family. The data code 0751 indicates a resistance of 750 Ω (4‑digit code: 0751). The suffix KL encodes the tolerance and temperature/coefficient class per the vendor’s datasheet. This part is intended for low-profile, low-power circuits on compact PCBs.
Key specs (typical, from the datasheet):
- Package: 0402
- Type: Fixed resistor (SMD)
- Value: 750 Ω
- Tolerance/TC: indicated by KL in the part number (see datasheet)
- Power rating: 1/16 W (≈62.5 mW)
- Applications: biasing, attenuation, filtering, general resistance in compact devices
Where to look: vendor datasheets (e.g., Digi-Key, Mouser) for exact tolerance, TC, and land-pattern recommendations.
