SFU455A

FILTERS FOR AM APPLICATIONS 450–470kHz SFU/SFZ SERIES FEATURES s Center frequency range between 450 and 470kHz is available. Standard tolerance is ±2kHz. s For synthesizers, the types of center frequencies 450, 459 and 468kHz are available. Standard tolerance is ±1kHz. s The part numbers of the types for synthesizers are as follows: (In case of 450kHz) SFU450A3 (for contact to resistor) SFU450C5 (for contact to resistor) SFU450B14 (for contact to IFT) SFZ450HL3/JL3/KL3 SFZ450H3/J3/K3 (for contact to resistor) DIMENSIONS: mm SFU455A/C5/B 7.0 ± 0.3 3.5 ± 0.3 SFZ455HL/JL/KL 7.0 ± 0.3 3.5 ± 0.3 MARKING M 9.0 ± 0.3 MARKING M 9.0 ± 0.3 1.1 ± 0.1 0.8 ± 0.1 3.5 ± 1.0 0.5 ቤባ ቢ 1.75 ± 0.5 2.5± 0.2 2.5± 0.2 : EIA-J Date Code 0.25 0.1 Connection ቢ INPUT ባ GROUND ቤ OUTPUT 1.1 ± 0.1 0.8 ± 0.1 ቢባ ቤ ቧቦ ብ 3.5 ± 1.0 0.5 1.75 ± 0.5 2.5 ± 0.2 2.5 ± 0.2 : EIA-J Date Code 0.25 0.1 Connection ቢ INPUT ባ ቦ GROUND ቤ ብ DIRECT CONNECTION ቧ OUTPUT SPECIFICATIONS Part Number SFU455A SFU455C5 SFU455B SFZ455HL SFZ455JL SFZ455KL 3dB Band Width (kHz) 10 ± 3 5 ± 1.5 10 ± 3 4±1 5.5 ± 1 7±1 PART NUMBERING SYSTEM +9kHz off (dB) min.
