SMD & Radial MLCCs for Power, RF, and Industrial Circuits

Kingtronics International Company — Reliable MLCC Solutions for Global Engineers

Multilayer Ceramic Capacitors (MLCCs) are vital for stability, EMI filtering, and precise energy control in electronic systems. To address global lead time challenges, Kingtronics® offers SMD and Radial MLCCs with fast delivery, stable supply, and highly competitive pricing — providing engineers a trusted alternative to leading global brands.

Kingtronics MLCC product overview — HKT, BKT, LKT, and MKT series

1. Why Stable MLCC Supply Matters

Industry studies show that MLCC availability directly impacts production schedules and cost control (ScienceDirect: Ceramic Capacitors Overview). Kingtronics ensures consistent raw material procurement, automated production, and predictable lead times, even during component shortages, supporting uninterrupted production for OEM and ODM partners worldwide.

2. Comparing SMD and Radial MLCC Structures

LKT — SMD Chip MLCC

The LKT series provides reliable capacitance stability in compact packages, ideal for consumer electronics, telecom boards, and computing systems requiring miniaturized components and reflow compatibility.

MKT — Radial (Leaded) MLCC

The MKT series uses a leaded, through-hole design with high mechanical endurance, suitable for industrial control modules, LED drivers, and power boards. Its standardized lead spacing supports automated insertion and long-term durability.

3. Advanced MLCCs for High Voltage and RF Systems

HKT — High Voltage MLCC

The HKT series supports voltages up to 5,000 V, featuring superior insulation resistance and dielectric reliability. Designed for power converters, lighting, and industrial control systems, HKT offers competitive pricing and short lead time, serving as a dependable alternative to globally known high-voltage MLCC brands.

BKT — High-Q / Low ESR MLCC

The BKT series provides Q-values above 2000 and ultra-low ESR, optimized for RF amplifiers, antennas, and microwave modules. It ensures minimal signal loss and high frequency stability for 3 GHz-class designs, with proven consistency across production lots.

X2 Capacitor 310VAC – Compare Kingtronics FKT-MX vs EPCOS, Kemet, Pilkor

Kingtronics International Company — Trusted Partner in EMI Suppression

When comparing X2 safety film capacitors, engineers prioritize reliability, certification, and delivery stability. Kingtronics FKT-MX (metallized polypropylene, 310 VAC) is a trusted alternative to Kemet R46 and EPCOS B32921–B32924, offering certified safety and consistent EMI suppression performance.

Key Specifications (at a glance)

The FKT-MX series is rated at 310 VAC and spans 0.0047 µF – 10 µF. It holds UL / ENEC / VDE approvals compliant with IEC 60384-14 for across-the-line EMI suppression. Designed for input filters in power supplies, lighting, and industrial controllers, it targets low loss ≤ 0.3% and thermal stability −40 °C ~ +110 °C.
