✔ RoHS Compliant / ✔ Package: 0402 / ✔ Authentic YAGEO Quality / ✔ Shipping from Shenzhen / ✔ Worldwide Delivery
Typical Applications & Hardware Integration
- Signal conditioning: Its 5% tolerance ensures acceptable accuracy in voltage divider circuits for signal scaling, while the 0402 package saves board space..
- Power supply decoupling: The 3.9kΩ resistance value is suitable for RC filter networks to suppress power supply ripple, and the 1/16W power rating handles typical dissipation..
- EMI suppression: With its small 0402 size, it can be placed close to IC pins to dampen high-frequency oscillations, and the 3.9kΩ value provides moderate impedance for filtering..
Key Technical Features & Advantages
- Wide Temperature Stability: Designed to operate reliably from -55°C to +125°C, suitable for harsh environments.
- Precision Resistance: The 0402 value resistance with ±5% tolerance guarantees accurate current control and signal integrity.
- Compact Form Factor: The 0402 package saves critical PCB space, enabling high-density designs without sacrificing performance.
