Shielding Circuits: Guard Against Surges

On January 19, 2024 in All, Circuit Protection, General by Littelfuse

Circuit designers have several options for protecting their circuit designs from ESD, transients, overvoltage, and overcurrent surges. Understanding how different protection schemes use other protection devices is key to safeguarding circuits.

USB Power Delivery Makes Circuit Protection Mandatory

On October 18, 2019 in All, Circuit Protection, Computing, Connectors by Steven Keeping

The additional voltage and current introduced to the popular USB standard by USB-PD multiplies hazards and makes circuit protection essential. But designing protection against all threats can be complex and expensive. Integrated solutions from chip makers simplify the task.

Keeping the Lights On: ESD and Thermal Protection for LED Lighting Systems

On January 29, 2019 in All, Circuit Protection, Lighting by TDK

There are several factors that can affect solid-state lighting including stress, packaging-related, and component-related issues. Discover the key threats that affect the reliability of LED lighting systems.

Protect Embedded Interfaces with These Clamps and Crowbars

On August 13, 2018 in All, Circuit Protection, IoT by Bourns

Protecting interface connections from overvoltage conditions and transient events is more important than ever with the proliferation of embedded electronics. Bourns clamp and crowbar protection is effective at protecting circuit interfaces in silicon and ceramic electronic components.

Protect USB Ports From Nefarious “USB Killers"

On April 11, 2018 in All, Circuit Protection, Computing, Memory, Power by Paul Pickering

USB ports supply both data communications and charging power to portable and wearable devices, so it’s become more and more critical to protect ports against abuse. Fortunately, there are design techniques that reduce power surge risks to USB ports.

A Conversation on High Operating Voltages

On December 9, 2014 in Circuit Protection by Kelly Casey

Like most professions, engineering has developed a language of its own. This is needed to convey very specific and precise information. Fuse design engineers, for instance, make a very clear distinction between an overload condition and a short-circuit condition. (Overloads are in the range of ~200% of the fuse's rating while short-circuits are 10X or more.)

The Surge Star Program

On January 23, 2014 in Circuit Protection by Kelly Casey

In this first post, I would like to talk a bit about the need for circuit protection in general. My view is that electronic devices should all have immunity to common surge events. That is to say, electronic devices should never fail due to ordinary and foreseeable electrical disturbances – be they ESD, induced lightning surges or incidental contact with AC power lines.
