High-Energy, Double-Sided Chip Resistor With Enhanced Pulse Performance

May 02, 2019 by Scott McMahan

TT Electronics announced what the company says is the first of its kind, high-energy, double-sided chip (HDSC) resistors, the latest addition to its range of pulse withstanding chip resistors. HDSC chip resistors are untrimmed for enhanced pulse performance, and the company claims that they are the only double-sided, untrimmed chip resistors on the market.

The HDSC resisters are suitable for industrial and medical applications indcluding power supplies, circuit breakers, and medical monitor input protection.

"HDSC resistors offer unique design value by providing better surge voltage and pulse power. These are tangible advantages for circuit designers who need enhanced surge protection in a compact SMD design," said Stephen Oxley, Senior Resistors Engineer, Applications and Marketing, TT Electronics. "HDSC's improved surge tolerance also enhances reliability and reduces field failures in applications exposed to electrical surges, critical factors in connected health and nonstop Industry 4.0 applications."

According to TT Electronics, the HDSC resistors are well-suited for replacing large-chip or multiple-chip solutions used to achieve pulse withstanding. The device features two parallel resistance elements in a single chip for improved pulse withstand performance.

The company says that the HDSC resisters reduce size and weight of designs while increasing surge protection for EMC regulatory compliance and product reliability. Their small footprint for given ratings saves PCB area in power conversion, motion control, and protection applications.

TT's HDSC resistors are available in four sizes from 0805 to 2512 and withstand up to 6.5kV peak for a 1.2/50µs surge and up to 6kW for a 0.1ms pulse. This product is designed for protection and discharge applications in compact power supplies and power control circuits where a resistance tolerance of 5% is suitable.
