Product Specifications & Quality Control
The datasheet lists important specifications of the ZA Series varistors, including their part numbers, voltage ratings, clamping voltage, energy, capacitance, and voltage tolerance. Detailed in Table 1, the ZA Series offers a variety of parts, such as M83530/1-2000B, M83530/1-2200D, among others, each designed for specific voltage and energy needs.
To ensure optimal performance and durability, Littelfuse integrates a comprehensive quality control regimen, with 100% testing for critical characteristics like high-temperature life, thermal shock, power burn-in, clamping voltage, and nominal varistor voltage, as specified in Table 2.
Further quality control inspections include visual and mechanical examinations, dielectric withstanding voltage testing, resistance to solvents, terminal strength, moisture resistance, and several others, grouped across three categories (Group A, B, and C Inspections).
Availability of Resources
For government use, Commercial Item Descriptors (CID) like CID AA-55564-3 are identified, making referencing and procurement easier. Additionally, further support is available in the form of datasheets, resources, and samples for interested users.
Note: The provided information is based on the 2014 specifications from Littelfuse and is subject to change. Interested parties should consult the most recent datasheet revisions for up-to-date details.
