MA-506 9 Series

epson

The MA-506 series from Seiko Epson Corporation is a lineup of surface mount crystals designed for a wide range of precision timing applications. These crystals operate within a frequency range that typically includes 32.768 kHz, which is common for watch oscillators and real-time clock (RTC) circuits. They feature a capacitance range of 18-20 pF and a temperature coefficient of ±50 ppm, making them suitable for applications requiring stable timing over a broad temperature range from -20°C to 70°C. Engineers often reach for these crystals when they need reliable timing components in environments with varying temperatures, such as in automotive electronics, industrial control systems, and consumer devices. The compact surface mount design makes them easy to integrate into PCB layouts, and their low power consumption and high stability ensure consistent performance even under thermal stress. One practical observation is that these crystals perform exceptionally well in battery-powered devices where power efficiency is crucial. Their low power requirements help extend battery life, which is particularly important in portable and wearable electronics. Another useful aspect is their robu
