ZTT-3.58MG

Overview

The ZTT-3.58MG is a ceramic resonator from the ZTT series manufactured by ECS Inc. It operates at a nominal frequency of 3.58 MHz with a frequency tolerance of ±0.5%. The component features a built-in capacitor of 30 pF and an equivalent series resistance (ESR) of 30 Ohms. Designed for through-hole mounting, it has a height of 7.50 mm (0.295 inches). The operating temperature range spans from -20°C to +80°C. This device is RoHS3 compliant and is currently classified as obsolete in the product lifecycle.

Feature Summary

• Integrates built-in capacitors to simplify circuit design
• Provides stable oscillation at 3.58 MHz with high precision
• Supports through-hole installation for robust mechanical connection

Applications

• Microcontroller clock sources
• Consumer electronics timing circuits
• Industrial control system oscillators

Procurement Notes

Verify component availability status carefully as this part is listed as obsolete. Confirm that the specific package dimensions and electrical parameters match the target design requirements before integration. Ensure compliance with RoHS3 standards if required by the final assembly specifications. Check for valid substitute part numbers if new production is needed.

Selection Notes

Select this component when a cost-effective ceramic resonator is preferred over quartz crystals for moderate stability applications. The built-in capacitor feature reduces external component count. Consider the ±0.5% frequency tolerance and 30 Ohm ESR characteristics against the system's timing accuracy needs. Verify that the through-hole form factor fits the PCB layout constraints.

Part Context

This component belongs to the ZTT series of ceramic resonators produced by ECS Inc. These devices are designed to replace quartz crystals in applications where slightly lower stability is acceptable in exchange for lower cost and smaller size. The series typically offers integrated capacitors to minimize external circuitry.
