2 Pole SMD MCF

1803C_NM7050SA_e This is a crystal filter that supports surface mounting. Adoption of a ceramic container has enabled the dimensions of the filter to be 7 x 5 x 1.35 mm. Supports a wide frequency range.

  • Supports IR reflow and VPS. (Contact us for information on the temperature profile.)
  • Supports surface mounting. (Packed with embossed tape)
  • Excellent heat- and shock-resistance.
  • Frequency range Fundamental: 20 to 90 MHz, Overtone: 60 to 150 MHz
  • Also supports 3 pole SMD MCF. ■ Features Model 21E7.5AD 21E15AB 21E30AD 21E7.5A 21E15AA 21E30AF Number of Poles 2 Nominal Frequency 21.4 MHz 21.7 MHz Stop Bandwidth Max. ±12.5 kHz at 15 dB Max. ±25 kHz at 15 dB Max. ±50 kHz at 15 dB Max. ±12.5 kHz at 15 dB Max. ±25 kHz at 15 dB Max. ±50 kHz at 15 dB Insertion Attenuation Guaranteed Attenuation Min. 60 dB at –910 kHz Min. 60 dB at –910 kHz Min. 50 dB at –910 kHz Min. 60 dB at –910 kHz Min. 60 dB at –910 kHz Min. 50 dB at –910 kHz Spurious Characteristics Min. 15 dB Within ±1 MHz Min. 15 dB Within ±1 MHz Min. 15 dB Within ±1 MHz Min. 15 dB Within ±1 MHz Min. 15 dB Within ±1 MHz Min. 15 dB Within ±1 MHz Operating Temperature Range –20 to +70 °C –20 to +70 °C –20 to +70 °C –20 to +70 °C –20 to +70 °C –20 to +70 °C Specification Number MN15-358 MN15-211 MN15-359 MN15-366 MN15-209 MN15-365 ■ Specifications Model 45E7.5AB 45E15A 45E30AN 90E9A Number of poles 2 Nominal frequency 45 MHz 90 MHz Stop bandwidth Max. ±25 kHz at 20 dB Max. ±25 kHz at 13 dB Max. ±60 kHz at 20 dB Max. ±50 kHz at 25 dB Insertion loss (insertion attenuation) Max. 2 dB Max. 3 dB Max. 2 dB Max. 5 dB Guaranteed attenuation Min. 60 dB at –910 kHz Min. 70 dB at –910 kHz Min. 60 dB at –910 kHz Min. 70 dB at –910 kHz Spurious characteristics Min. 10 dB Within ±1 MHz Min. 10 dB Within ±1 MHz Min. 5 dB Within ±1 MHz Min. 20 dB Within ±1 MHz Terminating impedance 200 Ω // 4 pF 1000 Ω // 4 pF 650 Ω // 1.5 pF 200 Ω // 8 pF Operating temperature range –20 to +70 °C –30 to +70 °C –20 to +70 °C –20 to +70 °C Specification Number MN15-367 MN15-297 MN15-369 MN15-226 mm GND GND OUTPUT GND GND INPUT Terminal land connections NM7050SA 7.0±0.2 1.35±0.15 5.0±0.2 5 4 6 – 1.2 6 – 1.0 2.54 3.94 2.54 6 – 1.4 6 – 2.2 6.0 2.0 Land pattern (Typical) ■ Dimensions Please specify the model name, frequency, and specification number when you order products.
