Applications
The Ohmite OY334KE is designed for precision and high-frequency circuit applications where standard wirewound resistors would introduce unacceptable inductive parasitics. Its non-inductive tubular construction makes it ideal for use in RF attenuators, power supply snubber networks, audio amplifiers, and industrial measurement equipment requiring stable resistance across a wide frequency range. The through-hole axial package with 38 mm leads also suits it for prototype boards, custom power assemblies, and repair applications where hand soldering is preferred.

Frequently Asked Questions
Why is the OY334KE described as non-inductive, and which circuit types benefit most from this characteristic?
The OY334KE uses a tubular non-inductive construction that cancels parasitic inductance inherent in standard wirewound resistors. This makes it especially valuable in RF attenuators, high-frequency filters, and pulse circuits operating above 1 MHz, where even a few nanohenries of stray inductance would alter impedance and degrade circuit accuracy. Instrumentation amplifiers and audio circuits also benefit from its low-inductance behavior across the audio band up to 20 kHz.
What are the physical dimensions and mounting style of the OY334KE resistor?
The OY334KE has a tubular body with a 7 mm package diameter and axial leads with a 0.8 mm lead diameter and 38 mm lead length. It uses through-hole mounting, which allows the component to be inserted vertically or horizontally into a PCB and soldered using wave solder or hand soldering. The 38 mm leads also provide enough length for chassis-mount or off-board installations in power assemblies and custom wiring harnesses.
Is the OY334KE compliant with RoHS and REACH environmental regulations?
Yes, the OY334KE carries a RoHS compliant designation (JESD-609 code e2) and is REACH compliant, meaning it is manufactured without the restricted hazardous substances including lead, mercury, cadmium, and certain brominated flame retardants. This compliance makes it suitable for consumer electronics, industrial equipment, and medical devices sold in the European Union, California, and other markets with strict environmental material restrictions.
How does the OY334KE compare to standard wirewound resistors in snubber and damping applications?
In snubber circuits placed across power semiconductors or transformer windings, standard wirewound resistors can resonate with the snubber capacitor at frequencies between 1 MHz and 50 MHz due to their winding inductance, reducing the snubber's effectiveness. The OY334KE non-inductive design eliminates this resonance, providing clean broadband damping of voltage transients and switching spikes, which improves EMI performance and protects power devices from overvoltage stress in switch-mode power supplies.
