The WALSIN WF04H1202DTL is a high-precision, surface-mount fixed resistor designed for demanding electronic applications. Manufactured in China, this resistor offers excellent reliability and stability, making it suitable for power supply, digital meters, PDA, computers, and palmtop devices.
Product Features
Small size and lightweight design for space-constrained applications
High reliability and stability under various environmental conditions
RoHS compliant and lead-free construction
High precision with resistance tolerance of ±0.1% or ±0.5%
Constructed with a high-grade ceramic (aluminum oxide) body and laser-trimmed resistive layer
Compatible with reflow soldering processes, including immersion in solder baths up to 260°C
The resistors are constructed with a ceramic substrate, internal metal electrodes, and a resistive paste that is laser-trimmed to achieve precise resistance values. The outer layer of the end terminations is tin (lead-free) alloy, ensuring ease of soldering and compatibility with surface mount technology. These resistors are tested for solderability, resistance to soldering heat, and thermal cycling to ensure durability and performance.
For more detailed specifications and application guidelines, please refer to the datasheet.
