Perfect High-Q MLCC Alternatives to ATC Capacitors

2025-07-20

When designing RF circuits, choosing the right high Q MLCC is critical for achieving low loss, stable capacitance, and outstanding frequency performance. Many engineers rely on ATC High-Q MLCC capacitors such as the ATC 100B and 200B series. However, with rising costs and supply chain volatility, finding a cost-effective, high-performance alternative has become more important than ever.

That’s where Hongda’s HRQ and HFQ series High Q MLCC capacitors come in — engineered to be a perfect replacement for ATC High-Q MLCC, offering equivalent electrical performance, excellent reliability, and broad size and tolerance selections.

Ⅰ. Why Choose Hongda High Q MLCC?

✔ Superior RF Performance

Hongda’s HRQ (and HFQ) series MLCC use C0G (NP0) dielectric, with a temperature coefficient of ±30ppm/°C, ensuring stable capacitance over a wide temperature range. They offer:

①High Q factors: minimizing energy losses in resonant circuits.

②Low ESR (Equivalent Series Resistance): ideal for maintaining sharp frequency responses.

✔ Broad Capacitance & Package Range

Available in popular sizes such as 0402, 0603, 0805, 1111, 2525, 3838, 0505, 7676, our High-Q MLCC series covers a wide capacitance range from tens to hundreds of picofarads, with tight tolerances down to ±0.05pF, making them well-suited for:

①RF matching networks

②Filters and couplers

③Impedance tuning

④Oscillators

✔ Non-Magnetic & Customizable Terminations

For critical RF and MRI applications, non-magnetic options are available, preventing signal distortion. Terminations include:

①Ag/Ni/Sn (lead-free)

②Ag/Ni/SnPb

③Non-magnetic versions on request.

Ⅱ. Typical Applications

Hongda HRQ and HFQ High Q MLCC capacitors are widely used in:
✅ RF amplifiers (LNA/PA)
✅ Wireless base stations (5G, LTE)
✅ GPS, WLAN, Bluetooth modules
✅ Radar and aerospace electronics
✅ Medical RF equipment & MRI coils
✅ High precision test instruments

Ⅲ. Why Hongda is the Best Alternative to ATC High Q MLCC

This makes Hongda’s High Q MLCC an ideal drop-in replacement for ATC parts in most RF designs.
