QA Technology 100-PRP4044S Probe, 0.100 Center, 0.400 Full Stroke, Crown, Standard SF, 100-40 Series

• High-current probe that carries increased electrical currents for dual level, loaded board testing.
• 0.100 center and 0.400 full stroke probe, part of QA Technology's 100-40 Series.
• Standard Spring Force (SF) made of stainless steel material with a 500,000 cycle life.
• Crown tip style (#44) is recommended when using a pin‑testable flux. A self‑cleaning crown or other multi‑point tip with valleys helps prevent contamination from building up.
• Tube material "P" nickel silver/id precious metal clad improves wear properties and offers < 20 mOhms resistance.
• Working temperature range of -55°C to 120°C with lubrication. SS springs can be used up to 204°C without lubrication.

The 100-PRP4044S, part of QA Technology's 100-40 Series, is a high-current and high conductivity probe. Configured with a 0.100" center and a 0.400" stroke, the standard force stainless steel spring ensures 500,000 cycles of dependable operation. Equipped with a Crown tip (#44), it's recommended when using a pin‑testable flux. Internally, the 100-PRP4044S's tube cladding improves wear and maintains < 20 mOhms resistance for accurate measurements. Thanks to QA Technology's patented plunger geometry, you get reliable electrical contact. Works from -55°C to 120°C, or up to 204°C for unlubricated stainless steel springs.

Questions and Answers

What is the maximum voltage that QA Technology test probes and sockets can carry?
There is no specific upper voltage limit defined for test probes or socket/termination pins. However, the spacing between probes and the dielectric strength of the probe plate must be evaluated. Probe plate materials that absorb moisture should be avoided. Apply test voltage to the fixture or DUT only after the fixture is engaged and the probes are fully compressed against the DUT. Energizing the probes before they make contact can cause arcing, which may damage or melt the probe tips.

Can QA Probes be used for Hipot testing?
Yes. Hipot testing, short for High Potential testing and also known as a Dielectric Withstanding Voltage (DWV) test, subjects a device to a voltage higher than its normal operating level. The purpose is to confirm that the device’s insulation can withstand this elevated voltage without breaking down, ensuring it provides adequate protection against electrical shock. This method is commonly applied to PCBs, transformers, electric motors, finished appliances, cables, and other wired or wireless assemblies.
