概述

Description

RK73H1HTTC4751F is a fixed surface‑mount resistor from the RK73H family (high‑stability thick‑film). The code 4751F decodes to about 4.75 kΩ with a tolerance of ±1% (F). The “H1H...TC” portion indicates a high‑stability part with a specified temperature coefficient (TC) per the datasheet (exact TC value varies by variant). This family is used where precision and stability are important, such as in voltage dividers, sensor interfaces, and calibration networks. For exact specs—power rating, maximum voltage, and the precise TC—consult the manufacturer’s datasheet for RK73H1HTTC4751F.

Features

Here are typical features of the RK73H1HTTC4751F (RK73H family) chip resistor:
- Very small SMD/thin‑film resistor for high‑density layouts
- Value code 4751F indicates a precise resistance with tolerance (F ≈ ±1%)
- High stability and low temperature coefficient (typical approx. 15–25 ppm/°C)
- Power rating around 125 mW (per element)
- Voltage rating commonly in the tens of volts range (typical ~50 V)
- Wide resistance range (ohms to megohms) with excellent long‑term stability
- Operating temperature range roughly -55 to +125°C
- RoHS compliant with reliable end-terminations suitable for automated soldering
Note: exact numbers (power, voltage, TCR) can vary by lot; consult the datasheet for precise specs.

Application

RK73H1HTTC4751F is a high-precision fixed SMD resistor (RK73 series). Applications: precision analog circuits and feedback networks in power supplies and motor drives; voltage dividers and reference networks; current sensing and biasing in automotive ECUs, telecom equipment, consumer electronics, and industrial control systems. Suitable for environments requiring tight tolerance and stable resistance over temperature.

Equivalent

I don’t recognize RK73H1HTTC4751F from the marking alone. Please provide the device type (resistor, capacitor, inductor, regulator, transistor, etc.), package/size, key specs (value, tolerance, voltage/current, frequency), a datasheet link or a clear photo of the part/board. With that I can list direct cross‑references (e.g., equivalent part numbers from Yageo, Murata, Bourns, Vishay) quickly.
