TDK EMC Filters for AC Power Line ZAG-M Series Datasheet

Category: Electronics, Passive Filters, TDK Corporation

Summary of TDK ZAG-M Series EMC Filters Datasheet

TDK’s ZAG-M series of EMC filters are engineered for single-phase AC power lines, complying with the RoHS Directive, which governs the restriction of certain hazardous substances in electrical and electronic equipment. These mid-size, box-cased filters boast a highly efficient thermal design that allows for high current handling capacity in a compact package. Notably, they provide superior EMC suppression characteristics which curtail both emission of and susceptibility to electromagnetic noise.

The ZAG-M filters are particularly adept in blocking both differential and common mode noise components. Their robust construction ensures that they withstand high voltages, offering AC 1768V between lines and AC 1500V between line and ground. This makes them reliable even in rigorous environmental conditions, including exposure to humidity, vibrations, and shocks.

Applications

These filters are designed for a broad range of electronics including computers, hard disk drives, electronic exchange devices, NC control devices, and large copiers. This wide applicability underscores their versatility in ensuring EMC compliance across diverse electronic and electrical systems.

Safety Standards and Part Numbers

One exemplary type within the series is the ZAG2250-M, which adheres to Canadian safety standard CSA C22.2 No.8 and bears the part number LR76849C, certified by the Canadian Standards Association (CCSA).

Technical Specifications

The ZAG2250-M is specified with a rated voltage of 250V and rated current, denoting its capacity to handle a defined electrical load. The filter is subjected to rigorous testing to measure its insulation resistance and to ensure minimal leakage current. Additionally, it exhibits low DC resistance and is capable of operating effectively across a wide temperature range, factoring in self-temperature rise.

The filter shows effective attenuation for noise frequencies in both differential and common modes, with a specified attenuation frequency range where it maintains a 30dB reduction in differential mode and a 20dB reduction in common mode.

Conforming to RoHS, these filters are manufactured without the use of hazardous materials like lead, cadmium, mercury, hexavalent chromium, PBB, and PBDE, except where exemptions are allowed. They weigh 1.5 kg, ensuring ease of integration into various systems without significantly impacting overall product weight.

The document cautions that specifications may change without prior notice, indicating that customers should verify the latest information before relying on the datasheet data.
