Carbon Composite Energy Absorption Resistors | PCB Energy Absorption Resistor Solutions for High-Pulse Power Systems

Image
Looking for a rugged, high-frequency energy-absorption resistor that mounts directly to your PCB? Our carbon-composite energy-absorption resistors—also marketed as PCB energy-absorption resistors—are engineered for designers who need to clamp mega-watt pulses without adding inductance or bulk. Key SEO Keywords: carbon composite energy absorption resistor, PCB energy absorption resistor, carbon composite resistor, high-pulse PCB resistor, energy dumping resistor Why Engineers Choose Our Carbon Composite PCB Energy Absorption Resistors • Truly Non-Inductive – Graphite/Al₂O₃ bulk construction keeps ESL <1 nH; usable to MHz frequencies. • Extreme Pulse Load Handling – Single-shot 2.8 kJ (CZ series) or 1.4 kJ (CY series) in a 25 mm footprint. • UL94-V0 Epoxy Seal – Moisture-proof and 150 °C continuous rated; survives traction and induction-heating environments. • Drop-In PCB Footprints – Standard 0.8–1.0 mm leads on 12.5–27 mm spacing; no heatsink required for sub-second pulses.

KP290~298 Power Wire-Wound Resistors

Image
  Product Overview KP290~298 is a radial-leaded, power wire-wound resistor family built on a glass-fiber core and finished with a high-grade silicone coating. The distinctive green or grey surface marking guarantees fast visual identification. Designed for continuous high-power dissipation, the series covers 2 W to 8 W in a single compact footprint line-up, making it the first choice for industrial motor drives, power supplies, welding equipment, UPS systems and white-goods inrush limiting. Key Features • High overload capability: glass-fiber core + silicone coating withstands 275 °C • Wide resistance span: 1 Ω – 9.1 kΩ in one series • Precision options: ±5 % (J) or ±10 % (K) • Excellent long-term stability: ΔR ≤ ±(5 %R + 0.1 Ω) after 1 000 h at 70 °C • Fully RoHS & REACH compliant, halogen-free coating • Flame-retardant coating to UL 94 V-0 Mechanical Dimensions Part Number Rated Power @70 °C Resistance Range L (mm) RM (mm) KP2900/1 2 W 1 Ω – 2.2 kΩ 18.2 10.2 KP2920/1 4 W 1 Ω ...
