About Non-Inductive Wire Wound Resistors

Non-Inductive Wire Wound Resistors

Features

Low Inductance

Applications

Used in Inductance Sensitive Circuits

Technical Specifications

A special technique of dual-opposing winding with adequate interlayer insulation can result in self inductance of a resistor being greatly reduced. This method known as the Aryton-Perry winding can bring down the inductance value to as low as 10% of the original value (had it been wound normally). In circuits which are sensitive to inductance which is inherently present in wire wound resistors, this series offers customers as low an inductance as possible. Such a feature is made available in wattage ratings upwards of 10 watts. Appropriate mounting hardwares can also be supplied for this range.

Advanced Reliability and Safety Features

The non-inductive wire wound resistors are built using high-quality ceramic cases and feature flame retardant capabilities in accordance with UL94V-0 standards. This ensures resistance to high temperatures and fire risks even under demanding operating conditions. Tinned copper leads and robust enamel coating add further protection against corrosion and mechanical stress, making these resistors ideal for long-term use in harsh environments.

Precision Performance for Electronic Applications

Their low-inductance, non-inductive design makes these resistors suitable for high-frequency circuits where signal distortion must be minimized. With tight resistance tolerances and high thermal conductivity, they offer reliable performance in precision circuits, power electronics, and measuring equipment. This enables accurate current limiting, sensing, and efficient circuit protection in both AC and DC applications.

FAQs of Non-Inductive Wire Wound Resistors:

Q: How are non-inductive wire wound resistors typically installed in electronic circuits?

A: These resistors are mounted using axial leads, making them suitable for through-hole installation on PCBs or chassis. The robust leads and ceramic body ensure secure attachment and consistent electrical connection.

Q: What specific benefits does the non-inductive design provide?

A: The non-inductive construction minimizes stray inductance, resulting in low noise and stable resistance across a wide range of frequencies. This makes them ideal for precision and high-frequency applications requiring accurate signal processing.

Q: When should I use a flame-retardant ceramic wire wound resistor?

A: Flame-retardant ceramic wire wound resistors should be used in environments where high temperatures, electrical overloads, or potential fire hazards exist, ensuring safer operation and compliance with UL94V-0 standards.

Q: Where can these resistors be utilized for maximum effectiveness?

A: They are most effective in precision circuits, power electronic devices, measuring instruments, and current sensing applications, particularly where moisture resistance and vibration proofing are required.

Q: What process ensures environmental compliance for these resistors?

A: These resistors are manufactured to be RoHS compliant, meaning hazardous substances such as lead and mercury are strictly limited, making them suitable for environmentally responsible installations globally.

Q: How does moisture resistance and vibration proofing improve the lifespan of these resistors?

A: High moisture resistance and vibration proofing protect internal components from environmental stress, reducing the risk of failure and ensuring reliable operation over extended periods, even in challenging conditions.
