HVC HVR Series: The Smart Drop-In Replacement for Caddock HV Resistors

Views: ...

Core Value: A 100% compatible alternative solution for Caddock MG, TG, TF, and USG series. We offer a more flexible supply chain and a superior cost structure, helping you break free from single-source dependency.

1. Why Choose HVC as Your Second Source?

In the face of global supply chain uncertainties, HVC (High Voltage Components) provides engineers with a mature "plug-and-play" solution.

✅ Pin-to-Pin Compatible: Strictly designed to Caddock's standard dimensions and pin spacing, allowing direct replacement without modifying PCB layouts.
✅ Excellent Electrical Performance:
- Low TCR: Standard TCR as low as 25 ppm/°C, comparable to Caddock TF series.
- High Precision: Offers multiple precision options from ±0.1% to ±1%.
- Non-Inductive Design: Utilizes a special helical cut process, demonstrating excellent performance under high-frequency pulses.
✅ Supply Chain Resilience: Ample stock of standard products, 2-week rapid delivery; custom products only require 4 weeks (compared to competitors' 12 weeks+).
✅ Cost Optimization: Bulk purchases typically save 15% - 25% on BOM costs.
