Main Characteristics of the YAGEO RC0805FR-074K7L

The RC0805FR-074K7L distinguishes itself with several core features critical to high-volume and high-reliability electronics manufacturing. It uses a halogen-free epoxy and is manufactured to be RoHS compliant, offering lead-free terminations to minimize hazardous waste. The resistor is part of the broader RC series, which covers a broad range of resistance tolerances (±0.1%, ±0.5%, ±1%, ±5%) and physical sizes for different engineering requirements. High component reliability, the use of non-forbidden materials in production, and MSL Class I stability ensure that the RC0805FR-074K7L can be trusted in both automated and manual assembly processes.

Design and Build Information for the YAGEO RC0805FR-074K7L

Designed with a robust construction, the RC0805FR-074K7L features a high-grade ceramic body as its substrate. Internal metal electrodes terminate at each end, providing stable electrical contact with the thick film resistive element. This element, composed of noble metal in a glass medium, is protected by a double-layered glass overcoat and a further protective epoxy coating to shield it from environmental stressors. Laser trimming of the resistive layer ensures tight tolerance, and external matte tin terminations over a nickel barrier guarantee solderability and corrosion resistance. This construction approach results in a device optimized for long-term stability and minimal drift in various operating environments.

Electrical Ratings and Performance Data of the YAGEO RC0805FR-074K7L

The RC0805FR-074K7L achieves a rated power dissipation of 0.125W (1/8W) at 70°C ambient temperature. With a resistance of 4.7 kΩ and a tolerance of ±1%, it is well-suited for precise voltage divider, pull-up, or signal conditioning roles. The resistor supports an operating temperature range from -55°C to +155°C, accommodating demanding industrial and automotive conditions. Rated voltage is determined by the formula V = √(P × R); for the RC0805FR-074K7L, this provides ample headroom for DC or AC (rms) operation, further enhanced by its proven moisture resistance. These characteristics ensure stable operation under both steady-state and transient circuit conditions typical in modern electronics.
