This document introduces the F1443B (V1.0) 10525 product from Shenzhen PowerOcean Technology Co., Ltd. It is a universal low-pass and band-pass active filter IC module suitable for low-frequency analog signal detection in industrial signal detection and medical electronic bio-signal detection. Its features include built-in high-precision capacitors, can be used to construct active high-order low-pass and band-pass filters, and are easy to design and use.
This manual describes the F14xxB series active filters, which are designed for ultra‑low‑frequency applications such as biomedical signal acquisition and precision instrumentation. It covers low‑pass, high‑pass, and band‑pass configurations with selectable cutoff frequencies from 0.1 Hz up to several megahertz.
The document includes detailed technical specifications, package dimensions, pin assignments, design equations for setting cutoff frequencies, and example circuits. It also provides tables of component values for Butterworth, Chebyshev, and other filter prototypes. This manual is written in Japanese.
| Frequency range | 0.1 Hz – 1 MHz |
|---|---|
| Accuracy | 1 % (30 ppm/°C) |
| Supply voltage (Vsup) | 4 V – 18 V |
| Operating temperature range | 0 °C – 70 °C (C銀), -40 °C – 85 °C (1銀), -35 °C – 125 °C (M銀) |

The filter operates from 0.1 Hz up to 1 MHz, covering ultra‑low to high frequencies.
Set R3 = R4 = Rf2 and C3 = C4 = 0.01 µF, then use Fc = 1 / (2π Rf2 Cf).
The filter can be powered with a supply voltage between 4 V and 18 V.
Internal components have a 1 % accuracy with a temperature coefficient of 30 ppm/°C.
