Visão Geral
Description
The RK73H1HTTC49R9F is an SMT fixed resistor from the RK73H family (a thick‑film chip resistor series). The code encodes value and tolerances:
- 49R9 = 49.9 Ω
- F at the end typically indicates ±1% tolerance
- The remaining letters (H1HTT...) denote temperature coefficient, termination/format, and package details per the manufacturer’s coding scheme.
Use: common in precision biasing, feedback, or signal conditioning in compact boards.
Notes:
- Exact package size (e.g., 0402/0603/0805), power rating, and TCR depend on the specific sub‑variant and manufacturer.
- For precise specs (max voltage, TCR, size, operating conditions), consult the official datasheet from the supplier.
