20pcs varistor 07D470K 47V piezoresistor 7D470K 7D470

Description

Product Overview

The 20pcs Generic varistor pack, model 07D470K rated at 47V, is engineered to provide robust surge protection across a wide spectrum of industrial and scientific applications. Each unit is a precision‑crafted piezoresistor, utilizing high‑quality ceramic and metal oxide materials that deliver consistent voltage clamping performance. The compact form factor allows for seamless integration onto printed circuit boards, while the 47V rating ensures optimal protection against transient over‑voltage events without compromising normal operation. Detailed specifications include a maximum continuous operating voltage of 47 volts, a peak pulse current capability suitable for typical industrial spikes, and a low leakage current that minimizes power loss. The pack is supplied in a convenient bulk package of twenty units, enabling cost‑effective redundancy and simplifying inventory management for manufacturers and maintenance teams. Designed with durability in mind, the varistors exhibit excellent thermal stability, resisting degradation even under repeated surge exposure, which translates to extended service life and reduced replacement frequency.

Usage

These varistors are ideally suited for deployment in power supply modules, motor control circuits, inverter systems, and protective assemblies within automation equipment. Their reliable voltage limiting characteristics make them a preferred choice for safeguarding sensitive electronics in environments where voltage fluctuations are common, such as manufacturing plants, renewable energy installations, and laboratory instrumentation. Installation is straightforward: the components can be soldered directly onto the board or mounted using standard through‑hole techniques, and their low profile ensures they do not interfere with adjacent components. The 20‑piece quantity provides flexibility for both prototype development and large‑scale production runs, allowing engineers to allocate spares for future maintenance or to implement parallel protection schemes for critical nodes. In addition, the varistors perform well in harsh conditions, tolerating temperature ranges from -40°C to +125°C, making them reliable for outdoor enclosures, automotive applications, and high‑temperature industrial settings.
