# HCCF3-10.700-LTCVS3L

**HCI (Suzhou HangJing Elec and Tech)** · Ceramic band-pass filter, 10.7 MHz · SMD 7.0 x 3.0 mm, 3 pads

HCI SMD ceramic band-pass filter for the 10.7 MHz FM IF: 180 kHz 3 dB bandwidth, 330 ohm input and output impedance. Terminate both ports in about 330 ohm for the specified passband shape. The LTCVS3 code corresponds to the HCCFV10.7MS3 row of the series datasheet (inferred from the matching bandwidth and loss; HCI does not print the cross-reference).

## Verification

A person checks each page against its datasheet and signs it off here; the badge turns amber if a checked file changes.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | passive | Input (datasheet p.1, HCCFV/A series drawing). |
| 2 | GND | passive | Ground, the middle pad. |
| 3 | OUT | passive | Output. |

**Note:** Ground is the middle pad, so a part rotated 180 degrees still lands ground on ground; input and output only swap, and a passive ceramic filter terminated equally at both ports has the same response either way.

## CAD

| File | What it is |
|---|---|
| `hccf3-10-700-ltcvs3l.kicad_sym` | KiCad symbol, with MPN, manufacturer and distributor numbers as properties |
| `hccf3-10-700-ltcvs3l.kicad_mod` | KiCad footprint: `AMFM:HCCF3_SMD-3P_7.0x3.0mm`, project library, LCSC land pattern |
| `hccf3-10-700-ltcvs3l.step` / `hccf3-10-700-ltcvs3l.glb` | 3D model, Z-up, seated on z = 0: LCSC / EasyEDA model (easyeda2kicad), EasyEDA logo stripped, seated on z = 0 |
| `hccf3-10-700-ltcvs3l-etched.step` / `hccf3-10-700-ltcvs3l-etched.glb` | The same model with the part number laser-etched on top as a separate, toggleable `Adom.LaserEtch` group (a virtual identification aid, not the maker's real marking) |
| `hccf3-10-700-ltcvs3l.lbr` | Fusion 360 / EAGLE library: one deviceset, each with its own MPN, manufacturer and LCSC / Mouser / DigiKey attributes |
| `altium/Adom_hccf3_10_700_ltcvs3l.SchLib` / `.PcbLib` | Altium library pair (adom-lbr, no Altium needed): symbol and footprint with the 3D body, parameters carry the part numbers; `altium/*.adom-lbr.json` is the canonical hub each was built from |

The 3D model comes from LCSC's EasyEDA library. Its embossed EasyEDA / LCEDA logo glyphs were removed with OpenCascade (`BRepAlgoAPI_Defeaturing`, then merging coplanar faces) and the body, pads, size and colours were kept; the source hashes, removed faces and before/after bounding boxes are in `page.json` under `component.provenance`.

The footprint points at `${KIPRJMOD}/hccf3-10-700-ltcvs3l.step`: copy the STEP next to your KiCad project (or edit the path).
