Solving the TDK Screw Terminal Capacitor Supply Crisis: HVC 100% Performance Match & Material Upgrade

Views: ...

Context: Since Murata's exit from the high-voltage screw terminal capacitor market, TDK has become the near-monopoly global supplier. However, this has led to uncontrollable lead times (often 16+ weeks), environmental concerns with lead-based materials (Y5S/Z5T), and a dangerously fragile supply chain. HVC offers a "zero-risk drop-in replacement" powered by superior N4700 ceramic technology and proven engineering expertise.

1. Why HVC is the Ultimate Safe Haven for TDK Screw Terminal Capacitors

HVC (HVC Capacitor) doesn't just match TDK's UHV, FHV, FD, and TSF series—we provide a generational upgrade in performance and reliability.

The HVC Competitive Edge & Business Value:

  • Material Evolution: We utilize Class 1 (N4700) ceramic, a superior upgrade over TDK's Class 2 (Y5S/Z5T). In high-frequency pulse environments, HVC exhibits significantly lower dissipation and temperature rise, dramatically extending equipment lifespan.
  • Safety & Reliability: Our Copper Electrode process eliminates the risk of "silver ion migration" breakdown common in high-field environments with traditional silver electrodes, ensuring mission-critical reliability for CT medical equipment.
  • Future-Proof Compliance: While TDK's Y5S relies on lead exemptions, HVC N4700 is 100% Lead-Free, ensuring your products easily pass the world's most stringent environmental audits.
  • Supply Chain Control: Standard lead times of 4-6 weeks break TDK's delivery monopoly. Our high-end production lines are immune to the geopolitical and logistics volatility affecting traditional giants.
  • BOM Optimization: Achieve 20%-50% cost savings without compromising on performance, freeing up significant profit margins.

2. Direct Cross-Reference Guide: 100% Drop-in Replacement

HVC ensures all replacement models perfectly match TDK's mounting threads (M4/M5/M6), physical diameters, and electrical parameters, requiring zero modification to your existing molds or PCB layouts.

The following tables cover all standard models across TDK's UHV, FHV, TSF and FD series — 53 models with corresponding HVC replacement models. HVC uses N4700 Class 1 ceramic (lead-free, lower dissipation factor) to upgrade TDK's original Y5S/Z5T/Y5P Class 2 materials.
