RK73H1HTTC4751F

RK73H1HTTC4751F is a surface-mount thick-film resistor in the RK73 family. Value: 4.75 kΩ with ±1% tolerance (F). The H1HTTC prefix indicates a high-stability, low-TCR variant designed for precision analog circuits. It is RoHS-compliant and reflow-solderable. The exact package size and power rating depend on the RK73 sub‑series (check the datasheet). Common uses include bias networks, reference dividers, and sensor front-ends in precision instrumentation. For definitive specifications (exact TCR, wattage, and footprint), consult the manufacturer’s datasheet or distributor listing.

I can’t uniquely identify RK73H1HTTC4751F without the manufacturer/datasheet. It looks like a KOA RK73H-series thin‑film resistor network (4.7 MΩ, 1%). Common equivalents (match package, resistance, tolerance, tempco): Susumu RN73 series, Yageo RN73/RC series, Vishay Dale RN73. Verify pinout, size and electrical specs on datasheets before substituting.

Here are the typical features of the RK73H1HTTC4751F (RK73H series) SMD resistor:
- Resistance: 4.75 kΩ (code 4751) with 1% tolerance (F)
- Type: Thick-film, surface-mount resistor
- Tolerance: ±1% (F)
- Temperature stability: low TC (H1H indicates high stability; refer to datasheet for exact ppm/°C)
- Power rating: commonly ~0.25 W (RK73 family)
- Package: RK73H footprint (compact SMD) with robust epoxy coating
- Operating temperature range: wide (typical -55°C to +125°C)
- Compliance: RoHS compliant (lead-free)
Note: For exact TC (ppm/°C) and power/footprint details, please consult the official datasheet.
