YC324-FK-07221RL

YC324-FK-07221RL Description

The YC324-FK-07221RL is a high-performance resistor network from YAGEO's YC324 series, designed for precision surface-mount applications. This 4-resistor isolated array features a compact 2012 (0805 metric) convex long-side terminal package, measuring 0.200" x 0.126" (5.08mm x 3.20mm) with a low-profile height of 0.028" (0.70mm). Each resistor offers a 221Ω resistance with a tight ±1% tolerance and a ±200ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The device is RoHS3 compliant, REACH unaffected, and rated for MSL 1 (unlimited shelf life), making it suitable for industrial and consumer electronics.

YC324-FK-07221RL Features

• 4 isolated resistors in a single package, reducing board space and assembly complexity.
• 125mW power rating per element, ideal for low-power circuits.
• Convex long-side terminals for improved solder joint reliability.
• Tape & Reel (TR) packaging for automated pick-and-place assembly.
• Wide operating temperature range with stable performance due to low TCR (±200ppm/°C).
• High precision (±1%) for applications demanding accurate voltage division or current limiting.
