Crystal Filter 2 Pole MCF (Surface-mount Type) ■ Features 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 VSP. (Contact us for information on the temperature profile.) ● Supports surface mounting. (Packed with embossed tape) ● Excellent heat- and shock-resistance. ● Good guaranteed attenuation. ● Frequency range Fundamental: 20 to 90 MHz, Overtone: 60 to 150 MHz ● Also supports 3-pole MCF. ■ Specifications Model 21E7.5AD 21E15AB 21E30AD Number of poles 21E7.5A 21E15AA 21E30AF 2 Nominal frequency 21.4 MHz 21.7 MHz 3 dB Passband width Min. ±3.75 kHz Min. ±7.5 kHz Min. ±15 kHz Min. ±3.75 kHz Min. ±7.5 kHz Min. ±15 kHz 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 Max. 1 dB Max. 1 dB Max. 1.5 dB Max. 1 dB Max. 1 dB Max. 1.5 dB Ripple Insertion loss (insertion attenuation) Guaranteed attenuation Spurious characteristics Max. 2 dB Max. 1.5 dB Max. 1.5 dB Max. 2 dB Max. 1.5 dB Max. 1.5 dB Min. 60 dB at –910 kHz Min. 15 dB Within ±1 MHz Min. 60 dB at –910 kHz Min. 15 dB Within ±1 MHz Min. 50 dB at –910 kHz Min. 15 dB Within ±1 MHz Min. 60 dB at –910 kHz Min. 15 dB Within ±1 MHz Min. 60 dB at –910 kHz Min. 15 dB Within ±1 MHz Min. 50 dB at –910 kHz Min. 15 dB Within ±1 MHz Terminating impedance 1.5 kΩ // 5 pF 1.5 kΩ // 1 pF 2.5 kΩ // 1.2 pF 850 Ω // 6 pF 1.5 kΩ // 1 pF 2 kΩ // 1.2 pF 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 21E15AA-21.7MMN15-209 21E30AF-21.7MMN15-365 45E7.5AB 21E15AB-21.4MMN15-211 45E15A 45E30AN 90E9A Min. ±4 kHz 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 Max. 1 dB Max. 1 dB Max. 1 dB Max. 0.5 dB Max. 2 dB Max. 3 dB Max. 2 dB Max. 5 dB 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 2 1 NM7050SA 45E7.5AB-45M- 45E15A-45M- 45E30AN-45MMN15-367 MN15-297 MN15-369 90E9A-90MMN15-226 Terminal land connections GND 1 GND 2 OUTPUT 3 GND 4 GND 5 INPUT 6 1.35±0.15 200 Ω // 4 pF Ordering code 7.0±0.2 Min. 60 dB Min. 70 dB Min. 60 dB Min. 70 dB at –910 kHz at –910 kHz at –910 kHz at –910 kHz Min. 10 dB Min. 10 dB Min. 5 dB Min. 20 dB Within ±1 MHz Within ±1 MHz Within ±1 MHz Within ±1 MHz Terminating impedance Package type mm NM7050SA 3 6 5 Land pattern (Typical) 6–2.2 6–1.4 Min. ±15 kHz 2.0 90 MHz Min. ±3.75 kHz Min. ±7.5 kHz 4.0 45 MHz 3 dB Passband width Ripple ■ Dimensions 2 Nominal frequency Insertion loss (insertion attenuation) Guaranteed attenuation Spurious characteristics 21E7.5A-21.7MMN15-366 6–1.0 Number of poles 21E30AD-21.4MMN15-359 5.0±0.2 Model 21E7.5AD-21.4MMN15-358 2.54 Ordering code NM7050SA 2.54 Package type 4 6–1.2 6.0 cf12_111003_NM7050SA_e Crystal Filter ■ Characteristics Model : 45E15A Model : 45E15A ATT (dB) 1 10 2 20 3 30 4 40 5 50 6 60 7 70 ATT (dB) 8 9 80 90 –10 –5 0 5 10 –1.0 –0.8 –0.6 –0.4 –0.2 45MHz (kHz) 0 0.2 0.6 0.8 1.0 (MHz) Model : 45E30AN Model : 45E30AN 1 ATT (dB) 0.4 45MHz 10 2 20 3 30 4 40 5 50 6 60 7 70 ATT (dB) 8 9 80 90 –25 –20 –15 –10 –5 0 5 10 15 20 –1.0 –0.8 –0.6 –0.4 –0.2 25 45MHz (kHz) 0 0.2 0.4 0.8 1.0 (MHz) Model : 90E9A Model : 90E9A 1 ATT (dB) 0.6 45MHz 10 2 20 3 30 4 40 5 50 6 60 ATT (dB) 7 8 9 70 80 90 –20 –16 –12 –8 –4 0 90MHz 4 8 12 16 –1.0 –0.8 –0.6 –0.4 –0.2 20 (kHz) 0 0.2 90MHz 0.4 0.6 0.8 1.0 (MHz) cf13_100512_ch4590_e
