Ametherm’s SURGE-GARD Line of NTC Inrush Current Limiting Thermistors Now in Stock at Mouser

Ametherm announced that Mouser Electronics is now stocking the company’s SURGE-GARD™ series of NTC inrush current limiting thermistors, which Ametherm acquired from RTI Electronics in 2013. The components are available worldwide via Mouser’s award-winning website, www.mouser.com, and its comprehensive resource catalogs.

Manufactured in Ametherm’s Carson City, Nevada, facility, SURGE-GARD series devices, available from Mouser Electronics, are capable of handling high steady-state currents to 36 A and input energy to 250 J. Available in multiple leaded package options with maximum diameters from 7.6 mm to 31.75 mm, the components offer resistance at +25 °C (R25) from 0.4 Ω to 220 Ω with tolerances down to ±10%, maximum operating voltage to 265 VRMS, and beta from 3000 °K to 3965 °K.

Constructed of specially formulated metal oxide ceramic materials, RoHS-2- and REACH-compliant SURGE-GARD thermistors are optimized for a wide variety of applications that require inrush current limiting to reduce noise and circuit failure — including switching power supplies, AC motors, motor drives, audio amplifiers, and battery chargers. In these applications, the devices lower rectifier costs by reducing the required peak forward-surge-current rating.

Mastering High Voltage: The Importance of Accurate Test Equipment

This whitepaper underscores that precise calibration of high-voltage test gear — especially when measuring 1 kV–150 kV systems — is essential for safety, reliability, and regulatory compliance. It details measurement techniques (voltage dividers, step-down transformers, etc.), the impact of environmental and connection factors on accuracy, and why traceable calibration (e.g. to NIST / A2LA) is a must to ensure consistent, reliable results.
