PCB Mount Through Hole Metal Oxide Varistor 10D511K 10mm For Switching Power Supply

General Information Of The Through Hole Metal Oxide Varistor 10D511K

The MOV-10DxxxK Series of 10 mm radial leaded varistor devices protects against overvoltage transients such as lightning, power contact and power induction. The metal oxide varistors offer a choice of varistor voltages from 18 V to 820 V and Vrms voltages from 11 V to 510 V. The devices have a high current handling, high energy absorption capability and fast response times to protect against transient faults up to rated limits.

VARISTORS MANUFACTURING PROCESS

In order to guarantee top performance and maximum reliability, close in-line control is maintained over the automated manufacturing techniques. The manufacturing process flow chart shows each step of the manufacturing process, clearly indicating the emphasis on in-line control. Each major step in the manufacturing process shown in the Manufacturing process flow chart is described in the following sections:

MILLING AND MIXING Incoming materials are checked, weighed, milled and mixed for several hours to make a homogeneous mixture.

GRANULATION A binder is added to produce larger granules for processing.

PRESSING The surface area and thickness of the disc help to determine the final electrical characteristics of the varistor, therefore pressing is a very important stage in the manufacturing process. The granulated powder is fed into dies and formed into discs using a high speed rotary press.

FIRING The pressed products are first pre-fired to burn out the binder. They are then fired for a controlled period and temperature until the required electrical characteristics are obtained. Regular visual and electrical checks are made on the fired batch.

METALLIZATION The fired ceramic discs are metallized on both sides with a silver content layer to produce good low resisitive electrical contacts. Metallization is achieved by screen printing. Visual checks are made regularly and a solderability test is carried out in each production batch.

ATTACHING LEADS Leads are automatically soldered to the metallized faces and regular strength tests are made. Three types of lead configuration are available; one with straight leads, one with straight leads and flange, and one with kinked leads.

LACQUERING The components are coated by immersing them in a special non flammable ochre epoxy lacquer. Two coats are applied and the lacquer is cured. Regular tests to check the coating thickness are made.

ELECTRICAL TESTING (100 %) The voltage of each component is normally checked at two reference currents (1 mA and another according to the application). Any rejects are automatically separated for further evaluation.

MARKING All components are laser marked with type identification, voltage rating and date code
